WATERVILLE, Maine — Police are looking for a man who allegedly robbed a Walmart pharmacy Tuesday night and escaped with drugs.

Police Chief Joseph Massey said Wednesday police were called to the Main Street store at 7 p.m. Tuesday, but by the time police arrived, the suspect had escaped.

Massey said the man approached the pharmacist and engaged him in small talk before he told the employee it was a robbery and he had a gun.

The man demanded 30-milligram oxycodone pills, but the employee told the suspect they didn’t have any, and he subsequently demanded 15 mg oxycodone pills and got away with a small quantity, Massey said.

The man, described as between the ages of 27 and 32 and weighing 180-200 pounds, was wearing a gray polo shirt and blue jeans, not exactly the style of a pharmacy robber, Massey said.

“He made no attempt to hide his identification,” Massey said. “In all the other pharmacy robberies, the suspect always tries to seal his identity by wearing hoodies or glasses.”

The suspect was captured on video surveillance, according to Massey. Anyone with information should contact Waterville police at 680-4700.
